World IPv6 Day and the Internet of Things

Post from George O’Meara

SVP, US and Canada, Cisco Services

If you’ve been paying attention you will have heard that the world’s supply of IPv4 addresses is running out. While this isn’t a Y2K situation, it’s an important watershed in the explosive growth of the Internet.  As the world shifts from an Internet of People and Places to an Internet of Things the foundation of the Internet is changing from IPv4 to IPv6.

Is Cisco ready to address the issue?

We’ve had working IPv6 code since 1996 for starters.  So we have some very seasoned support engineers who can answer all your questions at the IPv6 Cisco Support Community site. If you need help assessing your business needs, you can use our professional service offerings to  preserve your investment, prepare for the impending change and implement a long-term planning process.

How does an IPv6 address affect your experience?

No one really knows the full answer. That is  why the Internet Society is sponsoring a global test run  of  IPv6 use on June 8th, known as World IPv6 Day. It’s an opportunity for many of the major technology industry players to conduct an unprecedented experiment by enabling IPv6 on the Internet.

In fact, next Tuesday, on May 17th you should tune into a free IPv6 Webcast to hear about steps you can take to prepare your network for World IPv6 Day.

What does this shift in Internet addresses mean to you and your business?

It means that IPv4 addresses will become increasingly expensive.   The Internet of Things has fueled tremendous growth in the number of devices which need a network address. It’s not just a PC at work and one at home as we had a few short years back. Today  everything needs addresses including your smart phone, tablet, the chips in your car, sensors in bridges and roadways, security cameras, IP phones and more.

In the not too distant future, smart devices, new applications and new businesses will only be issued IPv6 addresses. Make sure you’re ready for this change.

What can you do today?

  • Recognize this transition is real.
  • Educate yourself on the technology.
  • Find at least one application to migrate to IPv6.
  • Stage it out in phases on your network.
  • Build your confidence through experience to future proof your network with the assistance of Cisco Services.

As I said, this isn’t a Y2K situation. The Internet of Things won’t come to a screeching halt. But your business network, or your customers, may start to experience less than optimal service or connectivity due to the industry’s lack of knowledge about how old IP addresses and new IP addresses will behave together.

Don’t risk having “good enough” technology and products. Get involved with the biggest network transition of our lifetime and start your adventure with Cisco Services expertise.

Cisco IPv6 Sales and Customer Technical Training Series

Join Cisco for a technical seminar on planning for IPv6 transition. Along with Cisco technical experts and other customers, you will get an in-depth look at planning and technical considerations based on Cisco’s Preserve, Prepare and Prosper strategy. These workshops can accommodate between 40 and 50 people and will begin the week of May 23rd, 2011 and run through June 28th, 2011.

The topics of these technical sessions are as follows:

  • Project timelines
  • IPv6 planning and considerations
    • Readiness assessment (application and network)
    • What to ask of Service Providers
    • Transition strategies (dual stack, translation, tunneling, etc)
  • Requirements gathering and drivers
  • Migration challenges
  • What Cisco is doing for World IPv6 Day (optional)

These workshops are open to all theaters and segments, featuring:

  • Three hours of combined sales and customer training
  • Between two and four hours of hands on virtual lab training with Cisco’s GOLD lab

Customer-to-customer TelePresence sessions to share best practices (certain locations only)

Training will be hosted in the following cities:

IPv6 Testing Sites and Tools

So, World IPv6 Day is just under a month away.  You already have IPv6 connectivity, right?  How do you know that everything will work correctly when the big day arrives?  You will need to do some testing.

A number of enthusiastic engineers across the world have set up public IPv6 sites that you can use to perform all manner of tests.  I would like to tell you about some of my personal favorites, and invite you to tell me about your own.  Please note that Cisco manages none of the tools mentioned here, and as such cannot offer any assurances about their suitability for use on your network, so insert your own dire sounding legal disclaimers here before continuing.

Can You Connect?

For a quick “Am I Ready?” test, http:/ provides a simple Yes-or-No assessment of your web browser’s ability to access IPv6 enabled sites on World IPv6 Day.  Here is my attempt to connect with an impaired IPv6 tunnel:

Cisco Showcases IPv6 Leadership & Announces More Branch Innovations at Interop, Las Vegas

As many of you are aware, this week the Interop tradeshow is taking place in Las Vegas.

Did you know that Cisco is the primary sponsor of the show’s InteropNet?  InteropNet is a world-class, fully IPv6-enabled network powering the 15,000-attendee and 400-exhibitor tradeshow complete with dual-stack IPv6 capabilities to all capable endpoints. This is the first-ever show network to be “dual-stack” with IPv4 and IPv6 running side-by-side and it highlights Cisco’s IPv6 leadership.  For more info on our IPv6 activities, please click here.

In addition, those of you stopping by the Cisco booth (booth 1127) will notice demos of our latest solutions including the new Cisco ISR Cloud Web Security with Cisco ScanSafe solution announced today. This solution seamlessly extends ScanSafe Cloud Web Security to branch offices and provides scalable, centralized Web protection and malware detection on the Cisco ISR G2 branch router and requires no additional hardware.

With this solution, organizations can easily deploy cloud-based Web security and Web usage policies, enabling highly secure local Internet access for all branch offices and users while saving time, money, and resources associated with traditional hardware deployments. The cloud service delivery model and central user account administration also make Cisco ScanSafe easy to deploy, manage and maintain via remote IT staff.

IPv6 Transition Tricks using LISP (Location/ID Separation Protocol)

What would you say if I told you that one of the most visited websites on the Internet enabled IPv6 connectivity to their site in the course of an afternoon for zero dollars using existing Cisco hardware?  How about if I told you that the site was Facebook?  Most people would assume I was joking or exaggerating.  However, by using LISP, Cisco Certified Internetworking Expert Donn Lee pulled off this seemingly impossible feat and then presented a paper at the North American Network Operators Group (NANOG) about the experience.  You can even watch the video here.

What is LISP? 

Let’s start by understanding the problem that LISP solves.  An IP address serves two distinct functions:  It identifies the endpoint host, but also suggests the location because the high order bits identify the network on which the device is located.  If you move a device from one subnet to another, the address has to change since the device location changes.  The endpoint identification from the previous location gets lost when the device moves, unless some form of tunneling or mobility protocol is employed.
